Re: ’57 Golden Javelin – fuel consumption question

quote XR55:

You might try a 10 1/2 x 11 prop. It might be the motor is not up to the max. rpm at wot. It may be lugging with a 10 1/2 x 12 prop and using more fuel and running slower at wot.

I’m certainly up for trying different props…what kind of a gearhead would I be if I didn’t want to tinker? 😀

Would 1/2" of pitch make a difference? I see there’s a 385955 (Michigan 012023) that’s 10-3/8 x 11-1/2, but I can’t find an 11" pitch for this engine.

I found this: 377978 which is 10-1/8 x 11, but I’m not sure it fits this engine.

Anyone have any prop suggestions?
